REFRIGERATOR.

Specification of Letters Patent. I Patented July 10,191?.

Application led April 22, 1916. Serial No. 92,923.

To all 'whom t may concern.' Be it known that I, TOM M. ANDERSON, a citizen of the United States, residin at Mayer, in the county of Yavapai and tate of Arizona, have invented certain new and useful Improvements in Refrigerators, of which the following is a specification.

This invention has relation to refrigerators, and the nature and objects thereof will be readily apparent to those skilled in the art'to which it appertains, inthe light of the following explanation of the accompanying drawings, illustrating what I now believe to be the preferred embodiment, or mechanical expression, of my invention from among other forms and arrangements within the spirit thereof, and the scope of the appended claims. l

I-Iowever, an object of the invention is to provide a refrigerator lfor containing foods whichA the refrigerating medium consists of water and air circulated throughout the refrigerator, in a novel manner, whereby the temperature therein is i lowered by evaporation of the water in accordance with a well known principle.

Another object of the invention is to provide evaporating surfaces of large extent in a refrigerator of the character described, whereby the lowest possible degreeof temperature may be obtainable. l In addition to the foregoing my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they ap ear;

`igure 1, is a view in side elevation, partly in section, of a refrigerator constructed after the manner of my invention.

Fig. 2, is a central vertical section through the refrigerator.

Fig. 3, is a horlzontal section on the line 3-3 of Fig. 1, and

Fig. al, is a horizontal section 4.-4 of Fig. l.

With reference to the drawings my refrigerator comprises in its essentialsa substantially cylindrical body portion ll having a central vertical chamber 2 in which food to be preserved may be stored upon shelves 0r the like (not shown), access to on the line said chamber being had through the provision of a lateral opening 3 at the lower portion thereof, normally closed by an airtight door 4.

The walls of the .container thus formed are relatively thick so as to permit the provision therein of a pair of helical channels 5 and 6, concentrically disposed around the central chamber, and having their lower ends connected by the passage 7. The helical channels 5 and 6 extend in their convolutions throughout the length of the refrigerator, and one ofthe channel formations is relatively greater in diameter than the other so as to define partitions 8 between adjacent convolutions.

One of the channels is in connection at the l upper portion of the refrigerator with an air inlet 9 connected to the channel 6, and the other with an outlet 10 connected t0 the channel 5. 4Vlater' inlet pipes 11 are also connected to the channels at their upper portions.

In operation water is injected into the channels through the pipes 11, circulates through the convolutions of both channels and descends by gravity to the lower ends of the channels and into the outlet 12 in the passage-way 7 to a waste conduit. At the same time air under low pressure is forced into the upper portion of the channel 6, through the inlet '9 and thence throughout the convolutions of said channel to the lower end thereof, through thev passage-way 7 and thence upward again into ,the convolutions of the channel 5. The Water is not permitted to entirely fill the channels but form a space through which the air may be caused to circulate, in this manner causing the evaporation of the water and lowering the temperature of the refrigerator walls. rEhe eiliclency of this form of refrigerator may be greatly increased b forming the same of porous material an especially the walls of the partitions the through the pores of' the partition thereby exposing a greater surface for evaporation and aording a greater reduction of temperature. During the circulation of Water and ,air through the channels, the air within the chamber 2 becomes cooled and if desired a cover ma be placed over said chamber to prevent t e entrance of heated air.

While I have illustrated and described my invention with some degree of particularty, various ways of reconstructmg the water permeating same to employ the principle involved will occur to those skilled in the mechanical arts, I therefore reserve the riglht and privilege of changing the form of t e details of construction, or otherwise altering the arrangementof parts, without departing from the spirit of the invention or the scope of the ap ended claim.`

aving thus described my invention, what 10 I claim as new and desire to Asecure by Letters Patent is I A refrigerator including a body portion
